Effect of long-term ageing on properties of RAP inclusive WMA mixes

摘要: Abstract This paper is an attempt to enhance the long-term performance of Reclaimed Asphalt Pavement (RAP) inclusive dense bituminous macadam (DBM) mixes, in post ageing condition, via inclusions a Warm Mix Additive. Two sources with two inclusion proportions (35% and 70%) were considered. The effect both technologies (RAP & WMA) on various properties DBM mixes such as Marshall Stability, retained indirect tensile strength (wet dry), rutting resistance Cantabro abrasion loss studied. Inclusions WMA was found significantly improve aforementioned regardless type aggregate used. Moreover, RAP-WMA retain much its even after compared RAP-HMA mixes. RAP fraction up 35% may be used for without compromising mechanical durability same (as present study). Incorporation these would further ensure longevity worst conditions moisture.
